This paper presents a platform-independent method for packaging learning objects and learning designs. The method, entitled a Smart Learning Design Framework, is based on the MPEG-21 standard, and uses IEEE Learning Object Metadata (LOM) to provide bibliographic, technical, and pedagogical descriptors for the retrieval and description of learning objects. This method represents a powerful platform that allows seamless searching, sharing, rights management, authoring, and adaptation of learning objects. In addition, the Smart Learning Design Framework encompasses the concept of generic learning designs, which provides the framework for including, sequencing, and aggregating learning objects. This paper describes the approach and places it within the context of the broader research agenda undertaken by the authors. (Contains 6 figures.)
